1. US Airstrikes on Iranian Nuclear Facilities: What Happened?
On June 21, 2025, the United States launched a series of precision strikes against Iran’s top nuclear research centers at Fordow, Natanz, and Isfahan, claiming the action was necessary to prevent Tehran from reaching weaponization thresholds. US officials said intelligence suggested Iran was nearing 90% uranium enrichment—a red line for both Washington and Tel Aviv.
Key Facts:
- Targets included deep underground bunkers at Fordow.
- Israel is suspected to have shared actionable intelligence.
- Iran confirmed the attacks but denied any violation of the NPT.
- No public casualty figures, but “severe infrastructural damage” reported.
The Pentagon called it a “preemptive strike”, while Iran labeled it an “act of war.”
2. Iran’s Strategic Options for Retaliation
Iran’s military and intelligence apparatus is now under immense pressure to respond—but with calibrated restraint or unpredictable aggression?
2.1. Short-Range Ballistic Missiles
Iran has a depleted but still formidable arsenal of short-range ballistic missiles (SRBMs) capable of striking US bases in Iraq, Qatar, Bahrain, and the UAE.
“Middle- and long-range capabilities have been degraded, but SRBMs remain a real threat,” says Dr. Jean-Marc Rickli, Geneva Centre for Security Policy.
2.2. Proxy Warfare via Houthis, Hezbollah, and PMFs
Tehran can activate its regional proxies:
- Hezbollah (Lebanon) can escalate along the Israeli border.
- Houthis (Yemen) threaten Red Sea shipping lanes.
- Popular Mobilization Forces (Iraq) can strike US personnel.
Houthis have already signaled readiness to target US Navy ships in the Bab al-Mandab strait.
2.3. Strait of Hormuz: The Oil Choke Point
Iran may attempt to blockade or mine the Strait of Hormuz, through which 20% of global oil passes daily.
Techniques include:
- Naval drones and fast boats
- Sea mines
- Kamikaze swarm tactics by the IRGC Navy
Such a move would spike global oil prices, hitting economies worldwide.
2.4. Cyber Warfare Against US Infrastructure
Iran’s cyber units, trained with Russian and Chinese assistance, may respond via:
- Attacks on US utilities and pipelines
- Malware in financial systems
- Information warfare via disinformation campaigns
2.5. Economic & Diplomatic Sabotage
Rather than full-blown military action, Iran may also:
- Sabotage oil pipelines in Saudi Arabia and the UAE
- Leverage OPEC+ allies to manipulate oil supply
- Push international tribunals for US war crimes
3. Global Reaction: What the OIC, Allies, and Rivals Are Saying
Organisation of Islamic Cooperation (OIC)
- Condemned both US and Israeli “aggression”
- Called for a ministerial contact group to promote de-escalation
- Urged the UN to take “deterrent measures” against Israel and the US
European Union
- Urged restraint from all sides but refused to condemn the US action
- Reiterated Iran must not enrich uranium beyond peaceful use
China and Russia
- Strongly condemned the US, calling it a “violation of sovereignty”
- Offered support for renewed nuclear diplomacy without preconditions
4. Impact on Global Oil Prices and Energy Security
Any prolonged confrontation or the closure of Strait of Hormuz could send Brent Crude oil prices soaring beyond $150/barrel. That would trigger:
- Global inflation
- Recessionary fears in developing economies
- Supply chain disruptions in energy-intensive industries
5. Diplomacy or Escalation: What Path Will Iran Choose?
Iran is caught between a rock and a hard place:
- Not retaliating could project weakness and incite internal dissent.
- Retaliation may trigger further US-Israel military action.
US President Trump has urged Iran to “return to the negotiating table.” The offer: halt enrichment in exchange for sanctions relief.
However, Iran’s Foreign Ministry has stated:
“We never left the talks. It was Israel and the US who blew them up.”
6. Expert Commentary: Is Iran Weakened or Strategically Patient?
Lawrence Korb, Former US Assistant Defense Secretary:
“Iran’s nuclear program may not be obliterated. The real question is, how fast can they rebuild? Days? Months? The US will need to reassess the actual damage.”
Domestic Anger in Iran:
Despite internet blackouts, Iranians are venting:
- “30 years of oil money wasted in nuclear holes.”
- “US bombs peace into the region.”
State media warns: “All US assets are now targets.”
Important Notes Of Iran’s Response to US Strikes
The recent United States military strikes on Iranian nuclear facilities have sent shockwaves through the global political landscape, reigniting tensions in an already volatile Middle East. This unprecedented development raises significant concerns about regional security, the future of nuclear diplomacy, and the stability of international oil markets. Iran has vowed “everlasting consequences,” hinting at a wide array of retaliation strategies ranging from military action to cyber warfare and economic sabotage. Meanwhile, global powers and international organizations have reacted with urgency, calling for de-escalation amid fears of a broader conflict.
On June 21, 2025, the United States conducted a series of targeted airstrikes on Iran’s top nuclear research sites at Fordow, Natanz, and Isfahan. According to US defense officials, these strikes were necessary to halt Iran’s alleged progression toward weapons-grade uranium enrichment. Intelligence reports suggested that Iran was on the verge of reaching 90% enrichment levels—widely considered the threshold for nuclear weapons capability. The Fordow site, in particular, located deep underground, was said to have been heavily damaged in the assault. While the Pentagon termed the operation a “preemptive strike” aimed at safeguarding global security, Tehran described it as a blatant act of war and a violation of international sovereignty.
The response from Tehran has been swift and furious. Iranian leadership has convened emergency meetings of its National Security Council, and officials have hinted at a multi-layered retaliatory response. One of the most immediate and visible forms of retaliation could involve the use of short-range ballistic missiles (SRBMs). Although Iran’s medium- and long-range missile capabilities have been degraded in recent years due to sanctions and covert operations, its SRBMs remain potent. These missiles are capable of striking US military bases in Iraq, Bahrain, Qatar, and the United Arab Emirates, posing a serious threat to American interests in the region.
Another strategic avenue available to Iran is proxy warfare. Tehran maintains a network of allied militias and non-state actors throughout the Middle East, including Hezbollah in Lebanon, the Houthis in Yemen, and various factions of the Popular Mobilization Forces (PMFs) in Iraq. The Houthis have already issued statements threatening to target US naval assets in the Bab al-Mandab Strait. Hezbollah, meanwhile, could escalate tensions along the Israeli-Lebanese border, forcing Israel to engage on multiple fronts. These proxies offer Iran a deniable but impactful way to respond to the US strikes while avoiding direct confrontation.
Perhaps the most globally disruptive retaliation option for Iran would be to threaten or attempt to close the Strait of Hormuz. This narrow waterway is one of the most critical chokepoints for global oil supply, with over 20% of the world’s petroleum passing through it daily. Iran has the capability to disrupt this vital passage using naval mines, drone swarms, and fast torpedo boats operated by the Islamic Revolutionary Guard Corps (IRGC). A successful blockade or even the perception of imminent closure could cause oil prices to skyrocket, triggering inflation and economic instability worldwide. Energy markets have already shown signs of volatility, with Brent crude prices spiking in anticipation of potential supply disruptions.
In addition to conventional and proxy military options, Iran may turn to cyber warfare as a means of retaliation. Over the years, Iran has developed a sophisticated cyber arsenal, often in collaboration with Russia, China, and North Korea. Iranian cyber units could target critical infrastructure in the United States, including electrical grids, water treatment plants, financial systems, and major corporations. A coordinated cyberattack could create chaos and economic loss while maintaining plausible deniability, allowing Iran to strike back without triggering a full-scale war.
Iran could also consider economic and diplomatic sabotage. For instance, it might encourage its OPEC+ allies to manipulate oil supply in its favor, leading to price shocks that affect the global economy. Alternatively, Tehran could pursue legal and diplomatic avenues, pushing for United Nations resolutions condemning the US action or filing cases in international courts. Though less dramatic, these responses could build international sympathy for Iran’s position while putting pressure on Washington diplomatically.
The international reaction to the US strikes has been mixed but intense. The Organisation of Islamic Cooperation (OIC), which represents 57 Muslim-majority countries, held an emergency meeting in Istanbul where it condemned both the United States and Israel for what it termed “acts of aggression.” The OIC announced the formation of a ministerial contact group to engage with international stakeholders and promote de-escalation. The organization also called on the United Nations to take “deterrent measures” against further attacks and hold the perpetrators accountable for potential war crimes.
In Europe, reactions were more restrained. While the European Union urged all parties to exercise maximum restraint, it stopped short of condemning the United States. European leaders reiterated their long-standing position that Iran must not enrich uranium beyond levels required for peaceful energy use. This stance aligns with Washington’s red line but highlights a diplomatic tightrope that European nations must walk to avoid alienating either side.
China and Russia, on the other hand, issued strong condemnations of the US actions. Both nations emphasized the importance of respecting national sovereignty and warned that unilateral military action could destabilize the entire Middle East. They called for an immediate return to diplomatic negotiations and offered to mediate future talks between Washington and Tehran.
Domestically, the US administration has defended its actions as necessary for global security. President Donald Trump stated that the strikes were intended to “eliminate an imminent threat” and urged Iran to “choose peace over provocation.” However, critics within the United States and abroad have questioned the timing and legality of the operation. Former Assistant Secretary of Defense Lawrence Korb noted that while the strikes may have damaged Iran’s nuclear infrastructure, they did not necessarily obliterate it. According to Korb, the real issue is assessing how quickly Iran can rebuild its nuclear capabilities and whether the US will allow that process to continue unchallenged.
Inside Iran, public sentiment is charged with anger and resentment. Internet restrictions imposed by the government have not stopped citizens from expressing their outrage on social media via proxy servers. Posts from Iranian users reflect deep frustration over decades of economic mismanagement and the futility of nuclear ambitions that have now drawn foreign attacks. State media, meanwhile, is fanning nationalist fervor, with anchors declaring that “all US citizens and military personnel are now legitimate targets.”
Iran now finds itself at a critical juncture. Retaliation could restore national pride and deter future aggression, but it risks provoking a devastating military response from the United States and possibly Israel. Conversely, choosing restraint may preserve Iran’s physical infrastructure and open the door for renewed diplomatic engagement, but it could also be seen as a sign of weakness domestically and among regional allies.
The diplomatic route, while fraught with challenges, remains a viable option. Iran’s Foreign Ministry has stated that it never withdrew from nuclear negotiations and blamed the collapse of talks on Israel and the United States. However, for diplomacy to resume meaningfully, Iran would likely need to accept stringent conditions, including halting all domestic uranium enrichment and sending enriched material abroad for processing. This demand is a hard sell for Tehran, which views its nuclear program as a symbol of sovereignty and technological achievement.
Expert opinions on Iran’s next move are divided. Some analysts argue that Iran is now strategically weaker than it was a few years ago due to the dismantling of its proxy networks and the degradation of its missile systems. Others suggest that Iran may opt for “strategic patience,” biding its time and launching a surprise counterattack once US defenses are relaxed. Options under consideration reportedly include cyberattacks, targeted assassinations, and sabotage of diplomatic or commercial missions.
The implications of this crisis extend far beyond Iran and the United States. Any escalation could drag in regional players like Saudi Arabia, the UAE, and Israel, all of whom have vested interests in curbing Iranian influence. A wider war could also disrupt global trade routes, especially in the Red Sea and Persian Gulf, affecting everything from energy supplies to consumer goods.
In conclusion, the 2025 US-Iran confrontation marks a dangerous escalation in a long-standing conflict. With nuclear diplomacy on life support and military tensions running high, the world faces a precarious moment. Iran’s response—whether immediate or delayed, military or diplomatic—will shape not only the future of the Middle East but also the broader contours of international relations. For now, all eyes remain on Tehran, waiting to see whether the Islamic Republic will choose the path of war or peace.
